Shimakaze (島風) (Island Wind) was an experimental destroyer of the Imperial Japanese Navy during World War II, and intended as the lead ship in a projected new "Type C" of destroyers. She was the only destroyer to be armed with 15 torpedo tubes, each capable of firing the deadly 610 mm (24 in) Type 93 "Long Lance" torpedo. The ship also served as a testbed for an enormously powerful, high-temperature, high-pressure steam turbine that was able to develop 79,240 shp (59,090 kW). This made her one of the fastest destroyers in the world: her design speed was 39 kn (72 km/h; 45 mph), but on trials she made 40.9 kn (75.7 km/h; 47.1 mph).
